Playful and informative, this book is perfect for any math or literature enthusiast. Feels like catching up with a smart friend over good coffee. The structure can be a bit jumpy, as if the author was saying "Here's a cool thing... and here's another cool thing..." but that only adds to the charm.

Prof. Hart also gives public/online lectures on fun topics like "the maths of B-movie monsters" and "how to prove 1 = 0 and other maths illusions" (details on her Gresham College web page).
